IMPRQVEMENT IN SASH-S'UPPORTER.

full and exact description of the same, reference bein had tothe accompanying drawings, and to the letters of reference marked thereon.v

This invention 'consists in an arrangement of cords,

pulleys, and springs, hereafter more fully described, by which arrangement the sashes of a window may be steadied and balanced at any height which may be de. sired, without the use of weights and catches.

` It is especially designed for thejwi'ndows of houses, but may be equally well applied to cars or coaches, or any moving structure, as its voperation is nowise interfered with by change of position or jarring of collision. `In order that those skilled in' the art to which my invention appertains may construct the same, I will proceed to describe its construction and operation, reference being hadto the drawings, an'd letters of reference written thereon, the same letters in the dii'erent figures marking different views of identical parts;

Figure 1 shows a front elevation of the sash, and frame which holds'it, parts bf the frame'being broken away to disclose the arrangement of the pulleys .and cords arranged thereon;-

, Figure 2 shows -a more particular view of thev construction'and arrangement of the pulleys and their connected cords. A is the sash, constructed in the ordinary manner. B is the frame of the window, differing from the ordinary frame only in the open spaces for the location of the pulleys, Vand the passages which permit the free play ofthe cords.'

' In both the iignres, a a a a are sheaves or' pulleys Y of thev ordinary construction, andb a similar pulley,

having two grooves on its periphery, `instead of one, as

in the'others.

C 0 are the cords, attached 'rmly to the upper and lower corners of the sash, at the outer edges of it, in such a manner as not to interferewith the easy passage of the sash in its frame; these cords'passng around the-.pulley s, as Ashown in' g. l, and being attached to a spring, D,in such a manner that the extreme elevation or depression of the sash will not bring the spring in contact vwith the pulleys, either above or below.

The spiing is made preferably -of coiled-steel wire, but may be of any permanentlyelastic material, and

is provided at its extremities with hooks or loops,` for connection with the cords.

'lheoperation of my invention is "as follows:

The upper cord G, being carried through between the double and single sheaves, over the single and through the second groove of the double, is' extended'down and attached to the spring. The .lower cord() is similarly arranged, except, for obvious reasons, the double pulley is omitted. The upper pulley may have its bearings in slots, so that when the pressure ofthe cord bears upon it, it will impinge againstthe lower or double pulley, and gripe the cord, in which case provision must be made for elevating the bearings, to relieve the gripe when the window is to belowered. These slotted bearings, however, are not an essential modification, and might be well applied, perhaps, to carwindows, where the upper cord would necessarily be attached to the lower part of the sash, making the upper sheave accessible, and where there might be unusual jar.

The cords being arranged closely, as above described,

it is evident that the sash willbe securely balanced, and may be elevated, and will remain stationary at any point, without the aid of props, or catches, or weights, and may easily and readily be closed or changed, with only the application of the hand to the sash. It will be obvious that the sash is held, by this arrangement, securely in place at all times, and without danger of rattling. Another advantage gained is, that there are no unsightly catches fastened upon any'part of the sash or frame. My device is cheaply and easily applied, and will not get out of repair, performing its functions until the ma terials of which it is composed actually wear out. The

described device is shown .only on one side of the sash# but may obviously be applied-to both..

Havingthus describedmy invention,

WhatI claim, and desire to secure by Letters Pat ent, is

-The construction and arrangement of the grooyed single .pulleys or sheaves c a, double sheave b, cords O C, and spring D, when applied to a window-sash and frame,- substantially as dfscribed, and for the purpose yset forth.

This specification signed and witnessed, this 18th day of March, 1868..
